Answer:
f(x) = 2^x
ln f(x) = ln 2^x
ln f(x) = x ln 2
Step-by-step explanation:
Answer:
7x + 2y = -22
Step-by-step explanation:
Standard form looks like Ax + By = C.
Start with Y = -7/2x-11. Better to write that as Y = (-7/2)x - 11 to emphasize that the coefficient of x is the fraction -7/2.
Move the (-7/2)x term to the left:
(7/2)x + y = -11
Multiply all terms by 2 to eliminate the fractions:
7x + 2y = -22 (answer)
We can simplify the exponent by multiplying 10 to itself 7 times.
= 10 * 10 * 10 * 10 * 10 * 10 * 10
= 100 * 10 * 10 * 10 * 10 * 10
= 1000 * 10 * 10 * 10 * 10
= 10000 * 10 * 10 * 10
= 100000 * 10 * 10
= 1000000 * 10
= 10000000
10^7 = <u>10,000,000</u>

Answer:
C. $19.65
Step-by-step explanation:
You have to find 20% of $98.25
This is equal to,
20% * $98.25 Because of usually means multiplication
= .20 * 98.25 Because .20 = 20%
= 19.65!
